SEEDING-MACHINE, CULTIVATOF?, AND HARROVV.

SPECIFICATION forming part of Letters Patent No. 270,414, dated .January9, 1883. Application tiled September Q3, 1F82. (Model.)

To all whom 'it may concern Be it known that I, GHAS. A. GEIGER, ofSpringfield, county of Clarke, and State of Ohio, have invented new anduseful Improvements in SeedingMachines, Gultivators, and Harrows, ofwhich the following is a full,clear, and exact descriiition, referencebeing had to the accompanying drawings, making part of thisspecification.

My invention relates to a novel arrangement,in connection withthedraw-bar and lifting-roller of a seedingdnachine or cultivator, ofpivoted hoe or tooth, and of the means for connecting said draw-bar andhoe or tooth with the lifting-roller, whereby the spring which holds thedraw-bar down to its work is adapted to hold the hoe or tooth in workingrelation to said `draw-bar; to the combination, with the rod, link, orchain which connects the draw-bar or the pivoted hoe or tooth withthelifting-roller, of a jointed self-locking pressure-bar for holdingthe hoe or tooth down to its work, and to certain details ofconstruction and arrangement hereinafter described. I In theaccompanying drawings, Figure l is a perspective view of so much of "agraindrill or seedingmachine as is necessary to show my improvements.Fig. 2 represents a vertical longitudinal section through the same; andFig. 3 is a view similar' to Fig. 2, showing a modih'cation in the formof the hoe or toothv and in the means for connecting the same with thelifting-roller.

A represents the frame of the machine, which may he similar inconstruction to such as are now in use in seedin'gmachines orcultivators; and B B', the main carrying and driving wheels7 appliedthereto in any usual or prc ferred manner.

C C' are the draw-bars, to which the hoes or teeth are pivoted, saiddraw-bars being connected at their forward ends with transverse pivot'edbeams or rock-shafts E E' for shifting the hoes or teeth from a singleline or row to a zigzag position or double row, and vice versa, in anyusual manner.

The hoes or teeth D or D' may he made in any usual or preferred form,according to the use to which they are to be applied, Whether for agraindrill, a broadcast seeding-machine, or a cultivator, and arepivoted at or near their upper ends to the rear. ends of the drawbars,which by preference are made double, or of bars parallel at their rearends and divergent at their forward ends for giving them a a broad hingeor pivotal connection with the rocking bars E and E.

The preferred form or construction of tooth or hoe is to provide it atits upper end with a forwardly-projecting arm, d, extending in advanceof the pivotal connection (indicated at tl') of the hoe or toothwith thedraw-bar, and frotn the forward end of this armd a link, F, or a chainor rod, F', extends upward, connecting said arm with a short crank-arm,g, on a transverse lifting roller or shaft, Gr.

The shaft or roller G is pivoted in suitable bearings in the sidelongitudinal frame-bars, and has a lever, G', either secured to itdirectly or geared to it. as shown, by a segmentrick and pinion forrocking it in said bearings, said lever being provided with a thumb`latch, operating, in connection with a toothed or perforated arch orsegment, on the frame for holding the lever G at any desired adjustment.

WherethelinkFisemployed-thatbeingthe preferred device-in connection witha grain` drill hoe or tooth, a slotted connection (indicated at f) ismade between the link and the arm g for permitting a slightindet'iendent movement ofthe teeth to accommodate themselves to -thesurface of the ground over which they are drawn, and the' slotpermitting this movement may be formed either in the link or in the armg, as preferred, the connecting-pin sliding in said slot being attachedto the other part. AWhere a rod is employed, as in dicated at F', Fig.3, it may be connected with the a-rm g of thelifting-roller in anysuitable manner; but for the purpose of allowing the independent risingand falling movement of the teeth referred to it is preferred to passits upper end through an eye or perforation in a. block, zf, swiveled inthe forked end 'of the -arm g. A pin or collar, f2, on the upper end ofthe rod prevents the rod and tooth from dropping too low, and a spring,interposed between the arm g and a collar ou tite rod be low said arm,serves to hold the rod down and to litnit its upward movement. Thisspring may extend the whole length ofthe rod be- IOO tween the arm g anda loose washer or collar,

'j, sliding,r on the rod F and resting on the drawbar J, as shown; ortwo short springs, t' and if', may bevemployed, one extending from thearm g to a fixed collar, f3, and the other from a fixed pin or collar,j, to the sliding collar or washer j. By this arrangement of springinterposed between the arm g of the liftingroller and thedraw-bar thelatter is held down to its work, and at the same time theforwardly-projecting arm d of the hoe is drawn upward by the tension ofthe spring on the rod F', thereby holding the hoe or tooth in properIworking,` relation to the draw-bar.

K. is a jointed pressure rod or bar, composed of two parts, k and It',the one, lc, pivoted to the arm g ot' the lifting-roller, or bypreference, where the slotted link F is employed, to the latter justbelow the arm g, as shown in Fig. 2,and the other, a,to the drawbar C inadvance ot the pivotal connection of the latter with the hoe or tooth,the adjoiningr ends of the two parts being hit'nrcated and provided withlockingr spurs or shoulders L l and a distendiug' spring, L, theconstruction of said parts being` by preference similar to thecorresponding parts of the jointed pressnre rod orbar described inLetters Patent No. 261,643, granted to J. \V. rlhomas, July 25, 1882, orin other equivalent form for the purposes therein described-viz., ot'forming,r a jointed pressure rod or bar provided with a self-lockingjoint.

By the construction and arrangementof the lifting-roller and theconnecting rod, lilik, or chain,and jointed pressure-rod connecting thedraw-bar and the pivoted hoe or tooth with said lifting-roller, it willbe seen that the hoe or tooth is held in proper workingr relation to thedraw bar, and both the draw-bar and tooth are held firmly down to theirwork, and at the same time each tooth is adapted to rise and fall withincert-ain limits independentlyot' the other hoes or teeth ofthe machine,and also to yield to obstructions, which would be liable to injure orbreak it. The means for adjusting the lifting-roller may be similar tothose described in Letters Patent No. 258Q24, granted May 30, 1882, toThomas and Ludlow, and the jointed pressure-rods may, if desired, beconstructed and arranged as therein described, or in any other suitablemanner attaining the results therein described. The arrangement of thepressure-rod and ot' the rod, link, or chain interposed between thelifting-roller and the draw-bar and tooth relatively to said draw-barand tooth may be varied, so long as they serve to hold the tooth inproper working: relation to the drawbar and the latter with the toothdown to its work.

Parts of the machine not particularly de scribed lnay be constructed andarranged in any usual or preferred manner.

Having now described my invention, I claim as new- I. In aseeding-machine or cultivator, a hoe. or tooth pivoted to its draw-bar,and provided with a forwardly-projecting arm connected by a rod, link,or chain with the lifting-roller.

2. In a seeding-machine or cnltivator, a hoe or tooth pivoted to itsdraw-bar, and provided with a forwardly-projecting arm connected by arod, link, or chain with the lifting-roller, in

combination with a spring the tension ot' which is exerted to hold saidhoe or tooth in working position.

3. In a seeding-machine or enltivator,a hoe or tooth pivoted to itsdraw-bar and connected by a rod, link, or chain with the lifting-roller,in combination with a jointed pressure-rod for holding said hoe or toothdown to its work.

4. A hoe or tooth pivoted to a draw-bar and connected by a rod, link, orchain willi the lifting-roller,in combination with ajointed pressure-rodconnecting the draw-bar with the lifting-roller, said pressure-rod beingprovided with a locking-joint and a spring which exerts its tension tohold said joint locked.

5. In a seeding machine or cnltivator, a spring arranged to exert itstension to hold the drawbar down to its work, and at the same time tohold the hoe or tooth in working relation to said draw-bar.

(i. In a' seeding-machine or enltivator, the combination of a draw-bar`a hoe or tooth pivoted to said draw-bar, alifting-roller, a lever forcontrolling said roller, a jointed pressure bar, and a rod, link, orchain interposed between the lifting-roller and the draw-bar and hoe,and a spring arranged to exert its tension to hold the draw-bar down toits work, and at the salue time to hold the hoe or tooth in workingrelation to said draw-bar.

In testimony whereof I have hereunto set my hand this 15th day ot'September, A. l). 1882.
